Description

Technical Field

[0001] This invention relates to the field of socket technology, and more particularly to a socket device, a plug-in device, and a charging robot vehicle system. Background Technology

[0002] The charging socket for a charging robot is a device used to charge the robot. Typically, a charging robot is equipped with a dedicated charging base or charging station. When the robot needs charging, it automatically returns to the charging base and inserts its charging plug into the charging socket. However, when the charging robot returns to the charging base and engages with the charging socket, there is a deviation error when turning or moving straight, which can cause the plug on the charging robot to not accurately align with the charging socket. Summary of the Invention

[0003] To address the above-mentioned problems, this invention proposes a socket device, a plug-in device, and a charging robot vehicle system.

[0004] The technical solution adopted in this invention is as follows:

[0005] This application provides a socket device, which includes: a base plate, a cover plate, a movable plate, a socket assembly, and a first elastic element;

[0006] The socket assembly is mounted on the movable plate;

[0007] The base plate and the cover plate are fastened together to form a movable space, and the movable plate is disposed within the movable space;

[0008] The first elastic element is disposed between the base plate and the movable plate, and the movable plate abuts against the cover plate. When the plug assembly that mates with the socket assembly is not inserted perpendicularly, the first elastic element is used to deflect the movable plate to adapt to the non-perpendicularly inserted plug assembly.

[0009] When the plug assembly is not inserted perpendicularly, that is, when the insertion direction of the plug assembly is not parallel to or coincides with the axis of the first current plug of the socket assembly, the second current plug on one side of the plug assembly will first contact and engage with the first current plug of the socket assembly. If the angle between the insertion direction of the plug assembly and the axis of the first current plug of the socket assembly is slightly larger, the second current plug on the other side of the plug assembly will not be able to contact and engage with the first current plug of the plug assembly, which will result in the plug assembly getting stuck.

[0010] By setting the first elastic element, when the plug assembly is not inserted perpendicularly, the movable plate deflects at a certain angle with the position that first contacts the first current plug of the plug assembly as the deflection center, so that the first current plug on the side that has not yet contacted the second current plug is parallel to or overlaps with the second current plug, so that the first current plug cooperates with the second current plug of the plug assembly, thereby realizing the self-adaptive function of the socket assembly when the plug assembly is not inserted perpendicularly.

[0011] In actual use, the socket device is vertically mounted on the charging equipment, and the first elastic element is horizontally mounted to achieve the self-adaptive function of the socket assembly in the front and rear directions.

[0012] Furthermore, it also includes a support and a guide frame. The base plate is slidably mounted on the support, and the guide frame is fixed on the movable plate. The guide frame is arranged in a figure-eight shape, with the larger end of the figure-eight guide frame located on the side away from the movable plate.

[0013] When the plug assembly is inserted, the guide frame contacts the plug assembly. The plug assembly has a component force acting on the guide frame and sliding along the base plate. This component force is used to slide the base plate, thereby enabling the socket assembly and the plug assembly to be inserted and mated.

[0014] Furthermore, the guide frame includes two guide arms fixed on the movable plate. The guide arms have a limiting section and a guide section connected to the limiting section. The guide section is used to contact the plug assembly and cause the base plate to slide under the action of the plug assembly.

[0015] The end of the limiting segment away from the guide segment is fixed to the movable plate by fasteners. When the plug assembly and the socket assembly are engaged, the limiting segment is used to limit the plug assembly.

[0016] Furthermore, the bracket includes a sliding shaft and mounting plates disposed at both ends of the sliding shaft for fixing the sliding shaft. The mounting plates are used to install the socket device to the device or wall to be plugged in.

[0017] A slider is fixed to the side of the base plate away from the movable plate. The slider slides in conjunction with the sliding shaft. The socket device is slidably mounted on the sliding shaft of the bracket via the slider.

[0018] In actual use, the figure-eight shaped guide frame and the sliding shaft are set horizontally to achieve the self-adaptive function of the socket assembly in the left and right directions.

[0019] Furthermore, it also includes a second elastic element, the first end of which is fixed to the base plate, and the second end of which is fixed to the mounting plate of the bracket;

[0020] When the base plate slides along the sliding shaft to both ends of the sliding shaft, the second elastic element is used to reset the base plate.

[0021] Furthermore, the sliding shaft includes at least two, which are spaced apart on the mounting plate, and at least two sliders are slidably disposed on each sliding shaft;

[0022] The second elastic element includes at least two, with the first ends of the two second elastic elements respectively fixed to the base plate, and the second ends of the two second elastic elements respectively fixed to the mounting plates at both ends of the bracket.

[0023] Furthermore, the second elastic element is a tension spring, and mounting posts are fixed on the base plate and the mounting plate respectively. The tension spring is fastened to the mounting posts and connected to the base plate and the mounting plate respectively through the mounting posts.

[0024] Furthermore, it also includes a buffer pad, which is disposed within the movable space. The outer wall of the buffer pad contacts the base plate and the cover plate respectively. The buffer pad has a concave space, and the movable plate is located within the concave space.

[0025] When the plug assembly and the socket assembly are plugged in, the cushioning pad is used to mitigate the impact force on the base plate and the cover plate.

[0026] Furthermore, the first elastic element is a conical spring, the buffer pad has a through hole, the large end of the conical spring passes through the through hole and abuts against the base plate, and the small end of the conical spring is fixed or in contact with the movable plate.

[0027] Furthermore, the socket assembly includes a socket mounting base, a third elastic element, a movable plate, and a first current plug disposed on the movable plate. The first current plug is used to cooperate with the plug assembly to achieve electrical connection. The movable plate is disposed on the socket mounting base through the third elastic element, and the socket mounting base is used to fix the movable plate.

[0028] In actual use, the third elastic element is set vertically or inclined on the longitudinal section to achieve the self-adaptive function of the socket assembly in the vertical direction.

[0029] This application also provides a plugging device, including a socket device and a plug assembly, wherein the socket device is one of the socket devices described above;

[0030] The plug assembly includes a plug mounting base, a guide plate, and a second current plug disposed on the plug mounting base. The guide plate is fixed on the plug mounting base. The second current plug is used to cooperate with the socket assembly to achieve electrical connection.

[0031] In actual use, the plug assembly can be installed on the charging robot vehicle, and the socket device can be set on the charging equipment and connected to the power supply device. The socket device is plugged into the plug assembly to charge the charging robot vehicle.

[0032] This application also provides a charging robot vehicle system, including a charging device, a charging robot vehicle, and a plug-in device. The plug-in device is used to realize the electrical connection between the charging device and the charging robot vehicle, and the plug-in device is one of the plug-in devices described above.

[0033] The beneficial effects of this invention are:

[0034] (1) By setting the first elastic element, when the plug assembly is not inserted vertically, the movable plate deflects at a certain angle with the position of the first current plug of the plug assembly as the deflection center, so that the first current plug on the side that has not yet contacted the second current plug is parallel or overlapped with the axis of the second current plug, so that the first current plug and the second current plug of the plug assembly cooperate, thereby realizing the self-adaptive function of the socket assembly when the plug assembly is not inserted vertically.

[0035] (2) When the charging robot car is turning or going straight, there is a deviation error. The first elastic element can be used to make the socket assembly rotate in the front-to-back direction and connect with the plug assembly. The guide frame can be used to make the socket assembly slide in the left-to-right direction and connect with the plug assembly. Alternatively, the third elastic element inside the socket assembly can be used to make the socket assembly float up and down and connect with the plug assembly. This provides comprehensive and multi-angle protection for the connection between the charging robot car and the charging equipment, thus ensuring the operating efficiency of the charging robot car system.

[0045] The present invention will now be described in detail with reference to the accompanying drawings.

[0046] like Figures 1-5 As shown, this application provides a socket device, which includes: a base plate 110, a cover plate 120, a movable plate 130, a socket assembly 140, and a first elastic member 150;

[0047] The socket assembly 140 is mounted on the movable plate 130;

[0048] The base plate 110 and the cover plate 120 are fastened together to form an active space 101, and the active plate 130 is set in the active space 101;

[0049] The first elastic member 150 is disposed between the base plate 110 and the movable plate 130, and the movable plate 130 abuts against the cover plate 120. When the plug assembly that mates with the socket assembly 140 is not inserted perpendicularly, the first elastic member 150 is used to deflect the movable plate 130 to adapt to the non-perpendicularly inserted plug assembly.

[0050] like Figure 5 and Figure 7 As shown, when the plug assembly 200 is not inserted perpendicularly, that is, when the insertion direction of the plug assembly 200 is not parallel or coincident with the axis of the first current plug 143 of the socket assembly 140, the second current plug 230 on one side of the plug assembly 200 will first contact and engage with the first current plug 143 of the socket assembly 140. If the angle between the insertion direction of the plug assembly 200 and the axis of the first current plug 143 of the socket assembly 140 is slightly larger, the second current plug 230 on the other side of the plug assembly 200 will not be able to contact and engage with the first current plug 143 of the plug assembly 200, that is, the plug assembly 200 will be stuck.

[0051] By setting the first elastic element 150, when the plug assembly 200 is not inserted perpendicularly, the movable plate 130 deflects at a certain angle with the position of the first current plug 143 that first contacts the plug assembly 200 as the deflection center, so that the first current plug 143 on the side that has not yet contacted the second current plug 230 is parallel to or overlaps with the axis of the second current plug 230, so that the first current plug 143 cooperates with the second current plug 230 of the plug assembly 200, thereby realizing the self-adaptive function of the socket assembly 140 when the plug assembly 200 is not inserted perpendicularly.

The buffer pad 190 has a concave space 191, and the movable plate 130 is located in the concave space 191.

[0066] When the plug assembly and the socket assembly 140 are plugged in, the cushioning pad 190 is used to absorb the impact force on the base plate 110 and the cover plate 120.

[0067] In this embodiment, the first elastic element 150 is a conical spring, the buffer pad 190 has a through hole 192, the large end of the conical spring passes through the through hole 192 and abuts against the base plate 110, and the small end of the conical spring is fixed or in contact with the movable plate 130.
